I still think we'll need an option.
Otherwise (with the current/trunk optimization), for each of these special
directories, ls -i reports different inode numbers depending on whether
it appears as a command line argument (in which case, ls must lstat
(or stat) it) or it is encountered as an entry in some other directory.
Besides, from a portability standpoint, GNU ls -i should continue to
work the same way it always has, wrt mount points: print what is usually
a `2' for each of them.
